TerraTrike - Wide Rover Seat Frame:
Designed specifically to give riders more room on the seat of their Rover, this product would replace the stock seat frame and seat mesh. It is a great solution for those who feel unsupported by the stock seat style on the Rover, and is compatible with all Rover generations.
Make sure to add the Seat Mesh (sold separately) in the options menu. The standard TerraTrike Seat Mesh will not fit this Wide Seat Frame.
